Abstract

PROBLEM TO BE SOLVED: To prepare a combination of caffeine and fructose, capable of conducting consumption saving and restoration of muscle glycogen, capable of increasing free fatty acids in the body, and therefore capable of accelerating fatty acid oxidation in the body, when exercises, such as sports, are performed. SOLUTION: This combination of the caffeine and the fructose useful for improving the energy metabolism during the exercises is based on the following perceptions: an idea that the fructose may be utilized for the sports has never been found yet by paying attention to its characteristic that it requires a long time, e.g. about 25 min, for being absorbed into the body; the caffeine is designated as a controlled substance for doping and therefore it is self-evident that the caffeine has effects on sport performance; a common point of both the caffeine and the fructose is that they can save the glycogen; the most important matter in the exercises is saving and accumulation of an energy source; the body fat is infinite as the energy source, but the glycogen is limited with respect to its amount accumulated in the body; the glycogen exists in the muscle, the liver, and the blood in amounts of about 350 g, 100 g, and 2 g, respectively, the total of which corresponds to about 1,800 kcal in calories and about 90 min in time; and how can save the consumption of the glycogen the amount of which is limited and accumulate the same is to ingest a suitable amount of the caffeine and the fructose.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Technical field to which the invention pertains] Combination of caffeine and fructose is the main purpose of improving athletic performance, especially endurance, by utilizing each characteristic.

[0002]

BACKGROUND OF THE INVENTION Caffeine is a legitimate substance that excites the brain, which is most commonly used in the world and is found in plants such as coffee beans, cola, cocoa beans, tea and herbs. Generally, children and women love chocolate and carbonated drinks, and men drink coffee during business talks and work. Athletes also take caffeine in various ways to improve athletic performance. Fructose is a natural sweetener that is often found in honey and fruits, and is particularly popular in Europe and the United States as a sweetener for diabetics. In Japan, demand for various soft drinks is already increasing. However, although caffeine and fructose have been reported in many studies on their efficacy in sports, no product has been developed that combines them to clearly demonstrate their efficacy in sports.

[0003]

The effect of caffeine to reduce muscle glycogen during exercise, to increase fatty acid oxidation in muscle, and to delay the absorption of fructose in the body, and to be an energy source without being affected by insulin Combining characteristics,
The challenge is to improve endurance during exercise.

[0004]

[Means for Solving the Problems] It has been reported that taking caffeine before exercise increases endurance for long-term exercise. Caffeine intake increases free fatty acids and continues to reduce muscle glycogen utilization during exercise. From this, the energy-producing effect of caffeine is caused by increased fat utilization. Caffeine also stimulates the brain to stimulate calcium reuptake in the sarcoplasmic reticulum. Some athletes use drinks for recovery from fatigue or as a so-called nourishing tonic in games. The purpose of use is to take caffeine with the idea of "getting well" and "getting motivated by getting hot", but caffeine is originally specified as a doping prohibited drug. Caffeine, a banned drug that is taken on a daily basis, is determined to be positive for doping when it is detected in 12 ml or more in 1 ml of urine. Because there are individual differences in caffeine absorption and excretion, it is not possible to determine the safe amount for ingestion, but in general,
Equivalent to drinking 6-8 cups of coffee within 3 hours. Another disadvantage of caffeine is toxicity.
Although the diuretic effect of caffeine is known, exercising in a hot and humid environment may impair conditioning. A large amount of caffeine intake
Prolonged competitive stress can cause morbidity, so it's important to keep the right amount and always pay attention. Fructose is named because of its high content in fruits. However, it is easy to think that all the sugar contained in fruit is fructose, but fructose is 3% of the total sugar contained in fruit.
Not too 0%, mostly sugar and glucose. Fructose is about twice as sweet as sugar, but it takes 25 minutes to raise blood sugar. By the way, it takes 5 minutes for sugar, 2 minutes for glucose, 5 minutes for honey and 10 minutes for starch. Originally, it is desirable to quickly absorb and become an energy source, but for exercise use, glucagon secreted from α cells from the pancreas and insulin secreted from β cells are greatly involved, so it is not easy to use There is none. Before exercise,
Regarding carbohydrate intake during exercise, the types of carbohydrates differ before, during, and immediately after exercise, and the ability to exercise changes depending on which type is ingested and when. However, in all cases, the quick absorption effect of carbohydrates is the subject of research presentations, and it cannot be said that attention has been paid to the characteristics of fructose. Fructose has a slow absorption time in the body,
The property of being absorbed and quickly converted to an energy source without the involvement of insulin is of paramount importance during exercise. In particular, taking 25 minutes for absorption is a very important factor. If you ingest fructose just before exercise,
It is important that you become energy without being involved in insulin after 5 minutes. Speaking of 25 minutes after the start of exercise, it is just the time when glycogen re-saving is necessary. You should take full advantage of the fact that this fructose is 25 minutes apart and that it is not affected by insulin. Enhance endurance during exercise by increasing muscle glycogen-saving caffeine, increasing fatty acidification in muscle, and synergistic effect by combining the effect of delaying fructose absorption in the body and the ability to become an energy source without being affected by insulin The purpose is.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The combination of caffeine and fructose of the present invention is combined with a known food or a food ingredient, a pharmaceutical carrier or an excipient by a known method to obtain a food which improves energy metabolism. can do. The food or food ingredient to be used is not particularly limited, and can be appropriately selected by those skilled in the art depending on the specific application for the purpose of saving muscle glycogen, increasing free fatty acids in the body, and re-saving energy. Also, the form of commercialization of caffeine and fructose is not particularly limited, and can be made into various individuals, shapes and liquids depending on the specific application. In order to exert the combined effect of caffeine and fructose of the present invention, particularly important is the problem of doping due to caffeine ingestion, and the amount of fructose per serving. The method of ingestion depends on oral intake. Coffee beans containing caffeine as an active ingredient should contain a suitable amount of fructose as coffee, and cacao beans should be taken orally by mixing a suitable amount of fructose as cocoa or chocolate.

[0006]

EXAMPLE In a submaximal exercise test for athletes who have been trained, triglycerides in athletes taking caffeine are reduced by more than 105% and muscle glycogen is reduced by 4%.
2% savings. It was confirmed that caffeine intake suppressed carbohydrate utilization (from 72 g to 52 g), while lipid oxidation was enhanced (from 14 g to 2 g).

[0007]

The main features of the present invention are that, for fructose, the absorption time in the body is slow, it takes 25 minutes to absorb it, and it is an energy source without being affected by insulin secreted from the pancreas. is. Research has already shown how important it is for carbohydrates to be an energy source without the effects of insulin during exercise for glycogen re-storage. Regarding caffeine, there have been many research reports showing that it saved muscle glycogen and significantly increased fat metabolism. This combination of the properties of caffeine and fructose is fully effective in improving endurance.
